基于Labview的刚性转子动平衡测试系统研究

Labview-based Dynamic Balance Measurment System of Rigid Rotator

动平衡测试系统采用Labview软件及NI数据采集卡,实现对小型刚性转子振动信号实时采集和动态性能分析.主要采用了影响系数法来设计程序,应用交叉谱和FFT分析振动信号的幅值和相位.

Labview software and NI Data Acquisition Card was used in the dynamic balance measurment system to analyse the real-time data acquisition and dynamic performance of the smalll size rigid rotator. The system used the influent coefficient method to design programs and the cross spectrum and FFT to an- alyse the amplitude and phase of vibration signals.
